Part Number: RS55261
Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to deliver a smooth, controlled ride for Ford Super Duty trucks. This twin-tube gas-pressurized shock is engineered to handle the demands of both daily driving and off-road excursions, providing a significant upgrade over factory dampening. Specifically configured for 4-inch rear lift heights, these shocks ensure your vehicle maintains stability and comfort even with increased suspension travel.
Features
- Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between low and high-speed impacts to ensure a smooth ride on uneven terrain.
- Twin-Tube Gas Pressure: A nitrogen gas charge provides consistent dampening performance and reduces aeration to ensure fade-free operation during heavy use.
- 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior corrosion resistance and structural integrity to ensure long-term durability in harsh environments.
- Polyurethane Bushings: High-performance mounting bushings provide improved vibration isolation to ensure a quiet and comfortable cabin experience.

Frequently Asked Questions
Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55261_n458) includes two rear shocks.
Will these shocks lift my truck?
No, these shocks do not create lift. They are designed to be installed on vehicles that already have a 4-inch rear lift kit installed.
What is the benefit of the RS5000X gas-pressurized design?
The gas pressure reduces the foaming of the shock oil (aeration), which ensures the shock maintains consistent dampening force even during rapid suspension cycling.
